For the next 6–8 weeks my weekdays are almost gone (family work). I can do Saturday–Sunday properly, maybe 7–8 hours each day, and almost nothing on weekdays.

I don't want to drop the attempt in my head already, but I also don't want a fantasy timetable. Has anyone done a two-day-a-week phase and then switched back to daily?

I had a month like that. I treated weekends as two long static sittings (one book each day) and used 20 minutes on weeknights only to read the day's paper headlines, not chapters. When weekdays opened up again I already had two subjects moving. It's slower, not a cancellation.

That's a useful way to look at it. I'll lock polity for Saturday and modern for Sunday till December and not pretend I'll do economy on a Wednesday night.
